//! This crates defines the type inference engine.
//!
//! - **Type inference.** The type inference code can be found in the `infer` module;
//!   this code handles low-level equality and subtyping operations. The
//!   type check pass in the compiler is found in the `rustc_hir_analysis` crate.
//!
//! For more information about how rustc works, see the [rustc dev guide].
//!
//! [rustc dev guide]: https://rustc-dev-guide.rust-lang.org/
//!
//! # Note
//!
//! This API is completely unstable and subject to change.

// STD IS BANNED IN THIS CRATE.
//
// `#![no_std]` above is the ban and the compiler is the enforcer: without `extern crate std;`
// there is no `std` in the extern prelude, so any `std::` path fails to resolve and the build
// stops. Do not add that line back to make an error go away - the error is the point. Whatever
// needed `std` either has a `core`/`alloc` equivalent, belongs in `ekostd`, or is a
// dependency that has to be replaced.
//
// The prelude is the part a grep cannot see: `Vec`, `String`, `Box`, `format!`, `vec!`,
// `thread_local!` and `println!` name no path. Under `#![no_std]` they resolve through `alloc`
// and `eko` instead, which is why those imports appear at the top of every file here.
